IMPROVEMENT lN CONDENSERS FOR GAS-WORKS..

The Schedule referred to in these Letters Patent and making part of lthe same.

I, PETER MUNZINGER, of the city and county of Philadelphia and State of' Pennsylvania, have invented an Improved Multitubular Water-Condenser for Gas- IVOrkS, of' which the following is a'speciiicatlon Nature and Object of the I nvcntion.

Description of the Accompanying Dra-icing.

Figure l isa perspective view.

Figure 2 is a perspective view of the lower tubesheet.

Figure 3? is a perspective view of the inlet-chamber.

Figure 4 is a vertical sectional View.

Figure 5 is a plan view partly sectioned.

Figure 6 is a sectional view of the tapering groundjoint for the tubes. i

Figure 7 is the old method of joining the parts of' a condenser by means of a lap-joint.

lGeneralDescription.

The condenser is divided into vertical sections A, as shown at b, fig. 4', each ot' which is subdivided into three compartments by horizontal sections, viz.: an inlet-chamber, B, a tube or con(lensing-chamber, C, and an upper chamber or passage, D. The inletchamber B and the tube or condensing-chamber C are. connected by means of the lower tube-sheet E, which has upwardly or downwardly-projecting flanges c, as the case may require. It iits snugly into the inletchamber, fig. 3, resting on thc. diaphragm or gas-deflector F. The flanges are pierced by a double row of holes, el d, as shown at iig. 2, correspomiing to the bolt-holes c inthe inlet and tube-chambers, as shown at fig. 1, by which the whole are firmly and securely 'The inlet and tube-chambers have outwardly-project-ing flanges j, by which they are fastened together, so that, if the Condenser should require enlarging, additional side or end-plates can be let in.

The tube or condensing-chamber C has a flange, G, 'formed around its inner-upper part for carrying the topv tube-sheet H.

The tubes I, through which the gas passes, are secured to either the upper or lower tube-sheet, or both,

by means of' a tapering ground-joint, g, as shown at tig. 6.

Heretot'ore theinlet-chamber and the lower tubesheet have been cast together, with bells or sockets, into which the lower ends of the tubes were inserted and sealed with lead joints.

The tubes require to be of very thin metal, that the surrounding water may produce a rapid condensation and cause the gas to drop its tar and ammoniacal liquor into the receiving-chamber B. The thinness of the tubes makes them liableto rust when one becomes defective, particularly in the center. 'Thesides ofthe v condenser require taking ont and the intermediate tubes removed before the defective one can be reached and the lead sealing melted. By the use of my ground taper jointthc tubeI can be driven from the lower tube-sheet through the upper sheet, and be taken out at tbeptop of the condenser, and be replaced without in .the least interfering with the other parts of the condenser. p

I am aware that cylindrical ground-'joints-have been used, the objection to their use heilig that the tube rusted in its socket, and could not bedriven out, which is not the case with the tapering ground-joint.

As shown at L, iig. 7, formerly the sides and ends of a condenser were connected bya lap-joint, which made it necessary for a workman to remove a number of tubes before getting at the bolts which hold the condenser together; by the use of my flanges the bolts are all on Vthe outside of the condenser.

The gas from theinlet M enters the receiving-chamber B, and is deflected by the parttimr F, which is water-sealed, up the first bunch of tubes into the chamber D, when it is deiiected by the second row of tubes, as shown by the arrows, fig. 4, until ithas traversed the entire number.

\Vl|at I claim as my invention is- 1. A mnltitubular condenser, with flange-attachments, for the purpose shown and described.

2. A mnltitubularcondenser, composed of the inlet- `chamber B, condensing-chamber C, chamber or passage I'), and the lower tube-sheet E, as shown and described.

3. The tapering ground-joint, for the purpose shown and described'. p

In testimony whereof', I hereunto sign my name to this specification in presence of two subscribing Wit- IICSSGS.Y
